The book begins with the word of the Lord that came to Micah of Moresheth in the days of Jotham, Ahaz and Hezekiah, kings of Judah, which he saw concerning Samaria and Jerusalem. Micah summons all peoples and the whole earth to hear, because the Lord God will be a witness against them from his holy temple.
The Lord comes out of his place, comes down and treads on the high places of the earth. Under him the mountains melt like wax before the fire and the valleys split open like waters poured down a slope. All this is for the transgression of Jacob and the sins of the house of Israel. Micah asks what is the transgression of Jacob and answers that it is Samaria, and what are the high places of Judah and answers that it is Jerusalem.
The Lord will make Samaria a heap in the open country, a place for planting vineyards; he will pour her stones down into the valley and uncover her foundations. All her carved images will be beaten to pieces and all her wages burned. Therefore Micah laments, goes barefoot and naked, howls like the jackals and moans like the ostriches, because Samaria's wound is incurable and has come to Judah, to the gate of Jerusalem.
Then the prophet lists towns of Judah with wordplays on their names, in a roll of mourning: tell it not in Gath, roll in the dust in Beth-le-aphrah, pass on in nakedness and shame, inhabitants of Shaphir. Disaster comes down from the Lord to the gate of Jerusalem, and Lachish is named as the beginning of sin to the daughter of Zion, and Moresheth-gath. The chapter ends calling Judah to make herself bald in mourning for her beloved children, for they will go into exile.
